Location > Snow Forecast Summary

We calculate the snow forecast summary by taking the snow forecast for the previous night plus the current day. The following snow forecast summary example has 8 inches for Friday...

  • Thursday Night = 2-4 inches = 3 inches
  • Friday Day = 3-7 inches = 5 inches
  • Friday Summary = 8 inches
As seen in the image at the top of the article, this would make Friday orange since the snow forecast is above 6 inches. The snow forecast summary calculation is shown this way since this is the snow that you would see/ski on that day.

  • Blue is snowfall under 6 inches
  • Orange is snowfall over 6 inches
  • Purple is mixed precip (snow/rain)
Precip %: The statistical probability of 0.01" inch (0.254 mm) or more of precipitation at the given area in the given 12-hour forecast.

  • Snow is blue
  • Rain is green
  • Mixed precip (snow/rain) is purple
Precipitation: The amount of forecasted precipitation. This would be the amount of liquid precipitation you would measure if you melted all of the snowfall.

  • Snow is blue
  • Rain is green
  • Mixed precip (snow/rain) is purple
Snow Level: The elevation above which snow will fall and below which rain will fall. The snow level will fall to lower elevations during periods of heavy snowfall and rise to higher elevations during periods of lighter snowfall.

Snow Ratio: The forecasted snow-to-liquid ratio. The higher the snow-to-liquid ratio, the lighter the snow quality, and vice-versa. 10:1 will be fun but feel a little heavy, 15:1 will offer some faceshots and feel pretty light, while a ratio of 20:1 will be incredibly light, almost like skiing through nothing but air.
